6 Claims.

v This invention relates to a mirror and more particularly t a shavingmirror, although, qf course, the mirror could also be used for otherpurposes. V

5 This is a contnuation in part of our co-pending application, nowPatent No. 2,058,603, dated. October 27, 1936.

An object of the present invention is to provide such a mirror which isextremely simple and nexpensive in construction so that mirrors madeinaccordance With the nvention can be sold ai; very low cost and in whichthe mirror is securely held by the clamping members constituting theuniversal joint.

provide such a mirror which is very attractive in appearance and inwhich substantialiy the full face of the mirror is usable, theconstruction permitting the use of a substeintially rimless mirror.

In the accompanying drawing:

Fig. 1 is a front elevation of a shaving mirror embodying our invention.

Fig. 2 is a vertica1 section, taken on line 2-2, Fig. 1.

Fig. 3 is a vertical section, taken on line '3-3, Fig. 2 and showing oneof the clamping members.

Fig. 4 is a fragmentary vertcal section, taken on line 4-4, Fig. 2.

Fig. 5 is a fragmentary horizontal section, taken on line 5-5, Fig. 4.

The mirror proper is shown as comprising a ciicular piece of plate glass15 having a beveiled. edge 55 and having its back slvered, as indicatedat l', althugh it Wili be understood that various other refiectivecoatings can be applied instead of silver. This mirror plate is providedwith a metal back i8 which conforms to the shape of the mirror andhas tsedge l9 turned around the edge of the mirror and engaging the beve] E6so that the metal back completely encloses the real side-of the mirrorandembraces the beve1 all around itsperiphery. The metal hacking may be.of :any 'form and finish, but apieasingfinish is achieved. by makng theback Another object of the present invention is to be made of othermaterials than metal, such as sheet pyroxylin plastic. 7

The clamping jaws 2| and 22 are preferably die cast and can be of anysuitable configuration and. the end 23 of the section 21 and the end 24of the section 22 are preferably quite broad and pointedyas bestillustrated in Figs. 1 and 3, so as to provdea reliable grip on theopposite flat facesof the mirror proper both vertcally and horizontaliy.By making the gripping portions 23 and 24 generally spade-shaped in thismanner it is apparent .that the field of the mirroris interfered.with tothe least extent. Theopposite end of theciamping jaw 2! is bifurcated;toprovide a c1aw 25and thecorresponding end. of the clamping jaw 22is'bifurcated to provide a s'imilar jaw 26. The two claws 25 and 26jointly provide a spherical recess 27 whch engages a-ball 28; Theclamping sections 28 and 22 are drawn tightly -together by a screw 29,

this screw 'tigh'tly 'clamping the mirror proper between thespade-shaped. ends of the clamping sections and alsofrictionallyelamping 'the ball 28 betweenthe claws 25 and 26 so thatwhle a universal joint is provided sufiicient friction is provided tohold the mirror in any position to which itmaybe moved.

"Where both the ball 28 and the claws 25 and 26 are plated. it has beenfound dificult to obtan the:riecessary'friction for supporting themirror in any adiusted position, inasmuch as plated metal is, of course,very smooth, especially chromium -plating which has no grain structureand is extremely slippery. In accordance With the present invention,therefore, the insice of each of the claws 25 and 25 is provided With ahorsesnoe-shapedgro'ove 55 in which is piaced a horseshoe-shaped facing55 of yielding material, such as cork, which provides the necessaryfriction betweenthe ball and the two claws. It is obvious, o f course,that this facing is not -necessarily horseshoe-shaped but can be of anysuitable form. V 4

"It has been found that the highly polished faces of the piate g1ass andmetal hacking prevent rarreliable grip between the two clamping sectionsand the mirror by frictional engagement aioneandthat a positive look isnecessary in order to prevent the mirror proper from being pul1ed freefrom the jaws. Thus, regardless of how much the screw 29 is-tightenedand 'regardless of What type of friction facing may be interposedbetween the two clamping sections and the mirror, the mirror Wii1 not bereliab1y 'held, T0 provide a positive interlock -between the mirrorproper and the clamping jaws the buttons 20 of the metal backng plate |8are provided and these buttons fit, preferably snugly, intocorresponding recesses 30 in the clamping secton 2L In the form of thenvention shown, five of such buttons and recesses are provided and thesehave been found to firmly grp the mrror and ho1d it against dsplacementsince t would be necessary to shear the buttons ofi before the mirrorcould be moved by a pull in a plane parallel with its face.

It s obvous that other forms of nterlockng means could be employed and anumber of such means are shown in our patent above mentioned.

The hall 28 is mounted on an integral stem 34 having an enlarged collar35, the lower end of the stem 34 beng threaded, as indicated at 36. Thethreaded end 36 of the stem 34 extends through the upper part 01 cap 31of the base whch is indicated generally at 38, this cap being preferablymade of the same type of sheet metal as the back 18 of the mirror andpreferably being round. In order to secure the stem securely to the cap31 of the base the stem projects through a central opening in the upperpart of the base and is held in postion by a nut 39, a sutable washer 40and look washer 4| being suitably inserted between the nut 39 and the1nside of the upper section 31 of the base.

'I'he undersde of the upper part or cap 31 of the base s open and its rms preferably beaded, as indicated at 42. The underside of the base isclosed by a circular plate 43 havng a downwardly projecting marginalbead 44 and an uprght marginal flange 45 Which fits into the upper part31 of the base and close to its bead 42. This bottom plate 43 ispreferably covered With a piece of felt 46 or h'ke material so thatthere is no danger of scratching a hghly polished surface on Which theshaving mrror may be placed. It Will be noted that the bead 44 of thebase plate 43 extends be- 1OW the bead 42 of the upper section 3'! ofthe base and nasmuch as the bead 44 is covered With fe1t it will be seenthat the mirror can be tpped a substantial extent without danger of themetal bead 42 injurng the surface on which the mrror is supported. Itwill be further observed that the bead 44 provides a space 41 betweenthe center of the base plate and the surface on which the mrror may besupported. In this space is arranged the head 48 of a locking sleeve 49,this sleeve beng internally threaded and screwing on the threaded end 36of the stern 34 so as to draw the base plate 43 and upper section 31 ofthe base toward one another. 'I'he head of the sleeve 49 s in the formof a thin annular flange whch encases the under side of the plate 43around a central opening provided theren for the jaw of the sleeve 49.

In order to permit of using a small base 38 this base is weighted. Forthis purpose a number of disks 50 of sheet metal havng openings in theircenters are arranged between the upper part 31 of the base and thebottom p1ate 43, the clamping sleeve 49 extending up through theseopenings. When the clamping sleeve 49 is tightened the rim of theuppermost plate 50 is drawn into tight engagement with the underside ofthe upper section 3 of the base, as best llustrated in Figf2, so thatthese plates are firmly held Within the base and there is no danger oftheir moving and rattlng. These plates 50 are preferably, of course,made of scrap metal or as a by-product of other manufactured articles.

From the foregoing it is apparent that; the present nvention provides ashaving mirror which is extremely attractve in appearance and is veryconvenient to use nasmuch as 11: is carried by a heavy base through auniversal connecton Which permits the mirror to be moved to any desiredangle but; at the same time holds the mrror at the adjusted angle wthoutfurther manipulaton. It Wll further be noted thai; substantially theentire face of the mrror is usable and that the invention provides ashavng mrror which 15 extremely simple and inexpensive so that it can beproduced and sold at low cost and at the same time s of rugged anddurable construction.
